N, ASSIGNOB To THE EDMUNDS &' JONES- A coRPonnTIen OF MICHIGAN:

Pass Dec. 26, 1911.

Application filed. July 27, 1910. Serial No. 574,066.

i To all may concern:

- will enable others skilled irfthe art to which bodies with thermf, which are apcrtured to receive the it app'ertains to make and use the'san'ie, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a partof this specification. i

This invention relates to lamp structures, and consists in the association and arrangement of parts hereinafter more fully set forth and pointed out in the claim.

"lheobject ofthe invention is to provide simple andetlicient' means for mounting lamps used in connection with automobiles upon their supporting brackets in a manner toinsnre rigidity and security. and at the same time minimize the expense; the arrzingement being such as to simplify the" operation of attaching the lamp and facilitate such 'operation..-

The above object is attained by the st rue;

ture illustrated in the accom )an in (ll'tUVv' ings, in which Figure 1 is an elevation of a lamp body made in accordance with my invention mounted on its supporting bracket. Fig. 2 is a; transverse section as on line 22 of Fig. t. Fig. 3 is a perspectiveview of one of the double standards shown in. Fig. 2. Fig. 4 is a plan view of the bracket shown in Figs. 1 and 2.

Referring to the characters'of reference, 1 designates the body of the lamp in the form of a cylindrical sheet metal shell; It has heretofore been the custom to provide lamp projecting lugs on the sides lines of the supporting fork. that are secured therein by setscrews threaded iii said lugs. In most instances the forks are provided with threaded stems which pass through the apertures in the supporting bracket and are fastened by'nuts which scrcv' thereon. This arrangement "is objectionable because of the necessity of providing the body of the lamp with the side lugs just described which oll'cr unsightly and awkward projections on said body that materially interfere with the cleaning of the lamp and which are further objectionable because of the fact that a variation in the. size of the lamp will oftentimes make ditticult the attachment of the forks thereto, requiring fitting and adjust me'nt.

By reason of my invention I am able to do away entirely with the side lugs on the. lamp body and with the separate supporting forks. tion I pierce the wall of the lamp body on he lower side to permit of the passage of the standards 2 therethrough which are adapted to stand in transverse parallel relation. The inner end of each standard is provided with-a relatively thin plate'3 which is curved concentric with the wallof the lamp body so as to lie closelyin contact t'here\\' ith, said plate being secured to the body wall in any suitable manner. 'prefer-' ably by soldering. as this means of attachment does not show upon the exterior sur--. face of the lamp. The standards 2 at their upper ends closely till the openings in the wall of the lamp through which they passand the distance between said apertures is such as to correctly space said standards so that their lower ends will readily pass through the apertures 4 in the head 5 of the bracket (3 which is adapted to be bolted to the frame of the car, not shown. The brackets (3 are of standard make, the distance between the holes 4 being in all cases uniform so that a. lamp -irovided with the standards 2 as shown, spaced in accordance with the distance between the holes 4 in said bracket, becomes at once a standard lampwhich is always ready to be fitted to any of the standard brackets. It will be noted that the end portions of the standards which pass through the apertures 4 of the,bracket are reduced and threaded, as shown at 7, and that above said reduced threaded portion there is provided a shoulder 8 which rests upon the upper face of the head 5 0f the bracket, said standards being firmly secured in place by means of the nuts 9 which screw onto the threaded depending ends thereof against the undct' face of said head.

By securing the supporting stt'indards to the inner face of the lamp-'lmdy, as herein shown, the exterior surface of the lamp' is relieved from all projections, leaving itclcan audsmooth. By means of the -relatitcly wide plate carried by the upper end In carrving out my inven-,

of the attaching standards which extend onto the inner wall of'the lamp body a conin through which the standards pass, said wall is materially strengthened and a ver secure and rigid construction is afforded.

Having thus fully set forth my invention,-.

what claim as new and desire to secure by tters Patent-,"is:

body 'of the amp to fix sald standards in properly spaced relation.

- In testimony whereof, I sign this specification in the presence of two witnesses.
